The NTAK09 1.5 Mb DTI/PRI digital trunk card is a standard-size IPE circuit card.

The NTAK09 provides 1.5Mb ISDN primary rate interface and digital trunk interface capability. The NTAK09 can be equipped with two daughterboards: the NTAK20 clock controller and the NTAK93/NTBK51 D-channel handler interface.

You can install this card in slots 1 through 4 in the MG 1000S. The card is not supported in the MG 1000S Expansion. Up to four digital trunk cards are supported in each MG 1000S.
